Genetic testing is done either in a clinical setting or as part of a research study.

Testing in a clinical setting usually involves fees both for the medical/counseling services as well as for the test itself, if a test is needed. Also, consultations for comprehensive family risk assessment and counseling usually occur only in face-to-face visits and not by telephone.

Anyone considering genetic testing should always receive genetic education and counseling from qualified professionals to ensure that he or she fully understands the implications of testing and gives informed consent. Many of the specialists in this directory provide genetics services in a clinical setting.

About Genetic Testing Research

Turning scientific discoveries into clinical care is a long process. Initially, genetic tests are conducted as part of research studies to help decide when the test should be done, how safe the test is, how well the test works, and how accurate it is. These research studies also determine how sensitive and specific the test is. Research studies also explore counseling issues and the psychological, social, economic, and medical consequences of testing or not testing.

Some cancer genetics specialists listed in this directory are only involved in research projects. Others are involved in clinical care and some specialists work in both settings. The purpose of many research studies is to answer scientific questions. Therefore, researchers may not provide test results or other clinical information to study participants and their doctors. If a participant takes part in a research study, testing is usually paid for by the study.

Check for studies from NCI's List of Cancer Clinical Trials that are accepting patients for genetics research. For more specific results, refine the search by using other search features, such as the location of the trial. General information about clinical trials is available from the clinical trials section of NCI's Web site.
